I meant to click restore graphics default. I accidently highlighted the repair tool and hit enter which triggered that. I thought at the time to just let it run. It has been 11 hours and 20% downloaded. I really don't need to do this. Was having a directx problem, which I was trying to fix, starting with the simplest solution.

Is there a way to stop this download? I have Windows 10.

Not terribly computer literate, so will need clear instructions, please. And thank you in advance.
